How to populate the "Parent" column in the "View Requests" Form for the Child Reuqest submitted from

Hi,

We have several Custom Concurrent Programs(Parent) which in-turn submits other Concurrent Programs (Child) using FND_REQUEST.SUBMIT_REQUEST API. Such Child Requests do not have the Parent Request's request_id in the "Parent"Column of the "View Requests" Form (also the parent_request_id column in the fnd_concurrent_requests table is -1 for these child requests). The objective is to display the "Parent" column with the parent_request_id.

I tried with sub_request parameter as TRUE for the fnd_request.submit_request API. But the child request does not run at all. The Phase and Status of the child request is "Inactive" and "No Manager" respectively.
